Time difference between Hardware Node and container.

During the distribution (redhat/centos) installer, you choose the timezone for your HN. The container template has its own preconfigured timezone. So, it is very possible for the zones to differ.

To resolve the problem, you should configure your container to have the same timezone as the HN. For example, if EST is your preferred timezone:

rm -rf /etc/localtime 2>/dev/null; unlink /etc/localtime 2>/dev/null
ln -s /usr/share/zoneinfo/EST /etc/localtime
vzctl exec 1041 rm -rf /etc/localtime 2>/dev/null
vzctl exec 1041 unlink /etc/localtime 2>/dev/null
vzctl exec 1041 ln -s /usr/share/zoneinfo/EST /etc/localtime

--> Debian:

o ' tzconf ' (as root) for interactive timezone change (it asks questions.)

You can find many more exciting timezones with:

find /usr/share/zoneinfo/ | more

Or, here is a shell script that will let you change the timezones in ALL of your containers:

#! /bin/bash
for f in `ls /vz/private`
vzctl exec $f rm -f /etc/localtime 2>/dev/null
vzctl exec $f ln -s /usr/share/zoneinfo/CST6CDT /etc/localtime
